A seal ring is an annular seal ring which is configured to be interposed between first and second members, and seals a gap between the first and second members. The second member is inserted into the first member, and reciprocates in its axial direction with respect to the first member. The seal ring includes an annular base part, an annular innermost end part, and a widening protrusion part. The annular base part has a radially exterior end to contact the first member. The annular innermost end part is integrally formed with a radially interior end of the base part to contact the second member. The widening protrusion part is integrally formed with the innermost end part, and protrudes with respect to the base part in the axial direction of the second member.

An example fitting includes: a fitting body comprising an exterior annular groove formed and configured to receive a retaining snap ring to couple the fitting body to a fluid line connector; a seal carrier slidably accommodated in the fitting body and having: (i) a first end face, (ii) a second end face opposite the first end face, (iii) a first annular groove formed in an exterior peripheral surface of the seal carrier, wherein the first annular groove is configured to receive a radial seal therein, and (iv) a second annular groove formed in the second end face, wherein the second annular groove is configured to receive a face seal therein; and a spring having a first end fixedly disposed within the fitting body and a second end interfacing with the first end face of the seal carrier such that the spring applies a biasing force on the seal carrier.

A sealing unit (28) that fits within the sealing unit opening (26) of a housing 22. The sealing unit (28) including a sealant arrangement (32) that define a plurality of cable ports (30). The sealing arrangement is also configured for providing a peripheral seal between the housing (22) and the sealing unit (28). The sealing unit (28) includes an actuation arrangement (31) for pressurizing the sealant arrangement (32) within the sealing unit opening (26). The sealant arrangement (32) includes a plurality of sealing modules (33a-33e) each sized to form only a portion of the pressure actuated sealant arrangement (32).

A device for sealing a space at a juncture between elements of a nacelle, the device being non-flammable by heat, having a predetermined shape, and having a proximal end configured to be inserted into the space to be sealed so as to seal it, and a distal end configured to be fastened to an element of the nacelle at a fire area.

Fireworthy sealants may have a variety of compositions and be made by a variety of techniques. In certain implementations, a fireworthy sealant may include a body comprised of a cured, tacky, soft, deformable non-adhesive gel. The gel body may have an upper surface, a lower surface, and a perimeter, wherein the upper and lower surfaces of the gel body, in an uncompressed state, define a body thickness. The sealant may, in an uncompressed state, be dimensioned to fit in a first opening between a wall and an aircraft component surface and deformable when under compression to fit in a second opening, smaller than the first opening. The sealant may be flame retardant and produce low smoke density and low smoke toxicity.

A termination fitting assembly for use with a conduit includes the conduit comprising a primary pipe positioned centrally within a secondary pipe along a longitudinal axis of the conduit and the conduit having an interstitial space defined between the primary pipe and secondary pipe. The termination fitting assembly includes an interior fitting having an inner wall and an outer wall, the inner wall sized and shaped for insertion into and sealing with the primary pipe, and the outer wall extending circumferentially around the secondary pipe of the conduit. The termination fitting assembly includes an annular channel defined between the inner wall and the outer wall of the interior fitting and in fluid communication with the interstitial space of the conduit and an exterior fitting positioned around the conduit.

Gasket seals for high pressure applications include retaining elements with inner diameter seal elements that interlock with the retaining element to provide resistance to movement in both axial and radial directions between the retaining element and seal element. High pressure sealing may be accomplished using a metallic core retaining element to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through an inner diameter dielectric sealing element, such as a polytetrafluoroethylene (PTFE) inner diameter sealing ring. Flanges of a joint in a fluid flow ling may be bolted together with the gasket seal interposed therebetween. In the event of pressure changes, the inner diameter seal resists being drawn into the flow line, and resists axial movement relative to the retaining element, through dual locking members that secure the seal to the retaining element.

Apparatus and method contemplating a high pressure fluid end assembly having a body defining a body bore and defining a recess in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the recess and configured to extend from the recess beyond the body bore to seal against the sealing surface formed by the closure.

Provides is an assembly for sealing a juncture of a cable in a wall. The wall includes at least one aperture. The aperture is used for coupling a connector comprised in the cable. A cable end is provided with at least one flange. The flange surrounds at least in part the cable end. The assembly includes at least one strain relief element. The strain relief element is configured, once in a position to cooperate with the wall and the flange, to press, directly or indirectly, the flange against the wall when the connector is coupled while the strain relief element remains attached to the wall, so that the flange surrounds, directly or indirectly, the aperture and prevents, directly or indirectly, any foreign matter from passing the juncture of the cable at the aperture.
